How to find out what process is loading the system?

Question

linux

Good afternoon everyone.
The problem is in the SUSE Linux 11 virtual machine. The system loads the processor at 100% at startup.
Judging by the system monitor, the download is only from the "md" process.
Tell me, what kind of process is this and how can I influence it without ruining the system?

Answer 1

There are suspicions that you are rebuilding a soft RAID array
Show cat /proc/mdstaton the host and virtual machine and htop sorted by CPU (or ps ax | grep md)

Answer 2

Cat gives everywhere:

# cat /proc/mdstat
